TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 470,874, dated March15, 1892.

Application filed April 20, 1883. Serial No. 92,316. (No model.)

T at whom it may concern.-

Be it known that CARLOS GLIDDEN, deceased, late of Milwaukee, in thecounty of Milwaukee and State of lVisconsin, did invent certain new anduseful Improvements in Type-\Vriting Machines; and I, PHEBE JANEGLIDDEN, his executrix, of the city, county, and State aforesaid, dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,making a part of this specification.

The invention of CARLOS GLIDDEN relates to type-writing machines andwill be fully described hereinafter.

In the drawings, Figure l is a perspective View of the said type-writingmachine. Fig. 2 is a vertical longitudinal section through the center ofthe same. Fig. 3 is a rear view thereof. Figs. 4 and 5 are details ofthe spacing mechanism. Fig. 6 is a detailin perspective of the mechanismfor connecting the keys with the key-levers. Fig. 7 is a detail in planof the same; Fig. 8, a like detail in section;

and Figs. 9 and 10,respectively,aperspective and a sectional view ofmodifications of the same. Figs. 11 to 16, inclusive, are variousmodifications of keys. Fig. 17 is an end view of one of theinking-ribbon reels, and Fig. 18

0 a like view of the other. i

A is the box of the machine. A is thetop plate of the same, and A is themetallic basket in which the type-bars play. On the rim a of this basketare secured small brack- 3 5 cts a, which are slotted longitudinallyforthe reception of the type-bars B and their operating-wires B, andthese brackets are bent up at their free ends, as shown, so that theymay guide the type-bars in their rise and fall.

0 On each four (more or less) of the brackets a is placed a flangedplate Z), that is perforated or slotted at its rearend to receiveset-screws that bind it, as well as its subjacent brackets a, to the rima. The bottom of each of the plates 1) is slotted in front to admittype-bars B and their mgerating-wires up through it and the flanges ofeach form the bearings for the pivots of the type-bars.

B are the key-levers, each of which pro jects back over a spring 0 andunder a stop 0 and is held in place between slats c c bya verticalspindle c, and then midway of its length is suspended by a staple (Z andwire B, that connects it with one of the type-levers. The key-levers arearranged side by side, and beneath them and forward of their centers issuspended a slat D, by both of its ends, from rods D and arms D thatproject from a rock-shaft E.

The rock-shaft E has a circular bearing in one side of the box A, andits opposite extremity is provided with a bottom notch to receive theupper edge of a knife-bearingf, the opposite edge of which rests in atransverse notch f in the upper surface of the lower arm of ahorseshoe-spring F, which by such lower arm is secured to the side ofthe box A at a point somewhat below the plane of the lower extremity ofthe basket, (see Figs. 2 and 3,) while a corresponding notch in theupper surface of the shaft receives the reduced lower extremity of aset-screw f, the body of which extends vertically downward through asuitable opening in the upper arm of such horseshoe-spring, the shaftbeing thereby clamped when the machine is at rest with rigiditysufficient to maintain its arms in a position in or somewhat aboveahorizontal plane therewith.

F is an elbow-lever, one end of which is keyed to the rock-shaft E aboutmidway of its length, while its other end lies parallel with the shaft Eand points in the direction of the horseshoe-spring F.

G is a frame that is journaled on one of its sides in hangers G, and hasa finger-shaft g journaled in its opposite side, the finger g of whichis designed to project up through the slot a in the top plate A, and togive the finger g a tendency to hug the left edge of slot a. The shaft gis surrounded by a torsionspring one end of which is anchored in theframe G.

H is a spacing-box, which is open at top and bottom and is grooved inits sides for part of its depth to receive spacing-plates h, and belowthe grooves the sides of the box extend down far enough to straddle alug h in the top plate A The arm of elbow-lever F, that is parallel 10:with shaft E, is connected on its upper side with the portion of theframe G thatisimmediately above it by means of a link i, which holds itagainst the tendency of the rock-shaft to raise the elbow-lever, and asthe finger g is carried by the frame as the latter is lifted by theelbow-lever it will thrust the finger up through the slot a in positionto engage with the spacing-plates h, as will be better described fartheron. The range of motion of the frame is regulated by a set-screw 7c andpost 76, as shown in Fig. 5, and the pin 1' is held in place by theupward pressure of the elbow-lever.

Just above the frame G and on the top plate A is secured lug 72, one endof which projects over the slot a and is slotted to-admit the finger gup through it, and this slotted end of lug his designed to abut againsteach spacing-plate h in turn and arrest the spacing-box and carriageafter each letter has been made. For instance, in Fig. 5 the slotted endof lug h is shown as abutting against one of the spacing-plates h andthe upper end of finger g is just beneath the same plate, this being theposition of the parts while there is a pressure on one of the keys tomake a letter, for as a key is struck it will depress a key-lever 13which, by depressing slat D, will draw upon rods D and arms D to rockthe shaft E, which will depress elbow-1ever F and permit frame G andfinger g to drop. Now when pressure is removed from the key the shaft E,being released, will return the elbow-lever F to the position shown inFig. 2, when it will lift the finger g, which in turn will lift thespacingplate that is immediately above it out of contact with theslotted end of lug It, so that the plate will pass over the lug, whichwill then abut against the nextone, which plate the edge of the upperend of the finger will also abut against, to yield. however, as thespacing-box and carriage advances, as shown in dotted lines, Fig.5,where it (the finger) will remain until another keyis struck, when itwill again fall back to the position shown in full lines, and so on inlike manner until the carriage has completed its travel, and then whenthe carriage is to be returned for another line the incline on top oflug h will permit the spacing-plates to ride freely back over it. I

A rod 1, which is suitably secured to the top plate A, passes throughsleeved lugs jj on the rear of the carriage, as well as through likelugs j on the spacing-box H, and as it fits loosely in these sleevedlugs the rod 1 forms a hinge as well as a guide for the spacing-box andcarriage; but to avoid binding the rear of the frame of the carriage isprovided with sheaves 1 that travel upon the rod I and support theweight of the rear portion of the carriage, the front of the same beingsupported by another sheave or roller 1 The frame of the carriagelcarries a cylinder-platen L, the axes of which are adapted to revolvefreely in their bearings and in the same frame, and just beneath therear portion of the platen L is journaled a roller L, which is designed.to hold the paper'in contact with the platen at that point and to causethe paper to hug the under side of the platen, and rubber bands Z areextended from about the grooves in the roller L to sheaves Z on a rod Ljust under the front portion of the platen L.

M are rounded arms that project one from each end of the carriage-frameon its rear, and on one of these is slipped the sleeved bearing on of abracket M, and on the other a like bearingm of another bracket'M Thebracket M is slightly curved, its highest point being that just in frontof its bearing m, and its lowest point just about its middle, and at adistance from its bearing-sleeve that is equal to about a third of itslength an armN is projected out from it, and from this arm the axle N ofan ink-ribbon reel N extends at an acute angle to bracket M. The bracketM like bracket M, extends with a slight downward curve out from itsbearing-sleeve, and from very near its rear end an arm N is projectedoutwardly and carries an axle N for reel M which lies at an obtuse angleto bracket M so that while the reels face each other their inking-ribbonwill be carried diagonally across the typewell, and therefore I thefirst letter on a line will take its ink from the front edge of theribbon and the last let-, I ter from the rear .edge of the same, and thuthe entire surface of the ribbon may be utili ized. v

The ink-ribbon M* extends at the right unj der the brackets M" and m andover the reel N while at the left it extends under the reel M and isheld taut thereon by means of the weighted triangular blocks n, whichare piv-' oted by their reduced or unweighted ends to the outer face ofsuch reel. As will be seen, Fig. 17, the weight of the ribbon tends tounwind it from the reel in the direction indi- 11o 'cated by the arrow;but this tendency is resisted and overcome or counterbalanced by theblocks n, one or more of which will in any adjustment of the reel restby its edge upon one of the pins n, which are arranged in a II 5 circleat suitable intervals a short distance within the periphery of the reeland which project outwardly from the end of the reel, and will thus beheld in such position that the weighted end of the same will projectbeyond the periphery of the reel and in the .direction of the body ofthe ribbon as it is extended across the well. After each line has beenprinted it is desirable, in order to produce clear letters in thesucceeding line, that the ribbon be advanced slightly, and in order thatthis may be done automatically a 7 plate 013, which is increased inthickness from its inner to its outer extremity, thus producing aninclined plane, is secured to the up- 1 0 per surface of the top plateA, its outer end projecting beneath the reel N Upon the axle N, betweenthe reel N and the arm N,

is sleeved one end of an elbow-lever 1, Figs.

1 and 18, the curved lower end 2 of which rests upon the upper surfaceof the inclined plate 71 To the elbow of the lever 1 is pivoted a pawl3, the play of which in one direction is limited by a guard or anysuitable stop l and in the opposite direct-ion by a springarm 5, thelower extremity of which is secured to the bracket M and the upperextremity of which extends upwardly between a ratchet c upon theperiphery of a circular plate 6 upon one face of the reel N and theopposite face of the pawl 23. In the operation of this portion of themachine, as the reel M is turned in unwinding the ribbon the blocks itupon the inner or ribbon side will bear by their edges upon theprojecting pins a, and their broader and heavier extremity will thus beextended outwardly beyond the periphery of the reel, while upon theouter or free side of the reel the blocks, being unsupported save bytheir pivot-pins, will fall to a vertical position and wholly within thevertical plane of the periphery of the reel. When the movement ofunwinding of the ribbon ceases, the blocks a will be in such positionthat those which are supported by the pins 72, as well as by theirpivot-pins, will overbalance the weight of those which are supported bytheir pivot-pins only to a degree sufficient to cause the reel to turnslightly toward the body of the ribbon and thus hold it with therequisite firmness against the platen. As the drawing of the ribboncontinues from time to time the weighted blocks will be successivelyelevated upon the inner or ribbon side of the reel and dropped to avertical position within its periphery upon the opposite side thereof,and will thus continually act to maintain the tension of the ribbonduring the operation of the machine. lVhen the carriage is turned downupon the top plate A of the machine, the

spring-arm 5 will also drop and permit the pawl 3 to again engage withthe ratchet *r of the plate 6; but this engagement will gradually ceaseas the carriage advances across the table, since the thickness of theplate 11 is diminished from its outer extremity toward the type-well,and this diminution permits the elbow-lever to be gradually depressedand thus carry the pawl out of engagement with its ratchet. Thus whenthe carriage is drawn back for an additional line the plate a willelevate the elbow-lever and cause the pawl to turn the ratchet and reelfar enough to bring.

a new surface of ribbon within the operation of the types for the nextline.

The front ends of the brackets h M are supported by rollers m to-insuretheir easy travel on plate m The carriage I is drawn over the top plateA by an upright K, the upper end of which is provided with a sheave 1*,about which a cord K is passed, one end of which is secured to the frameof the carriage and the other to the box A. The upright K is preferablyelastie, and its lower end is clamped by a loose knife-edge Z andset-screw I between the ends of a horseshoe-spring Y the set-screwentering the upright just above the knife-edge, so that when thecarriage is drawn back in position to begin a new line the ends ofspring K will be pried apart and their effort to return will give thedesired force for propelling the carriage. The spring operates upon thearm as upon a lever in which the loose knifeedge is the fulcrum and theset-screw the power which constantly causes the arm to assume a normalposition with suiiicient force to carry the carriage.

To enablean operatortoprintwithoutremoving his fingers from the keys,the key-levers B are arranged in groups of four, and a spindle O isprojected up from each of these levers to receive a sleeve 0, abovewhich the foot of a plunger P is loosely collared on each spindle, andeach four of these plungers is inclosed in a cylinder P, which ispartitioned off, so that each plunger slides in a barrel by itself.Above the partitions each of the cylinders is formed with a squared rim,each corner of which incloses partly the upper edge of a barrel andforms a guide for a keystem R, that is gimbaled in the bifurcated end ofa bracket S in such a manner that by manipulating the key its stem maybeguided into the barrel of any one of the plungers of the cylinderimmediately below it, and thus either one of the type-levers in a groupmay be struck, according as the key-stem is tilted forward, backward, orto the right or left as it is struck.

The key-brackets are projected from rods S, that are lifted bytorsion-springs S as in Fig. 6, or from staples S, as in Figs. 9 and 10,in which latter case they will. be supported by bent springs S and theirrange may be limited by fingers S and a slat S as in Fig. 6, or by asuperimposed slat S, Figs. 9 and 10, which latter figures also show amodification of the cylinder 1 and its connection with the levers BFigs. 11 to 16 show various forms of keys, any one of which is welladapted for the purpose; but when the machine is to be used by a personof deficient sight it is preferable to use a key having raised letters,as shown in Figs. 13 and 15.

Having thus fully described the invention of ARLOs GLIDDEN, what I claimas new, and desire to secure by Letters Patent, is-

1. In a type-writer, the spacing-box containing independentspacing-plates, in combination with slotted lug h, finger g, andmechanism, substantially as described, for con necting the fingerg' witha lifting-spring and the type-levers, as set forth.
